Evaluation of Spatial Efficiency of Xi’an Rail Transit Station Area Based on Data Envelopment Model (DEA)

The data mainly includes land use data of rail transit stations, passenger flow data of rail transit, social development data, and economic level data. Among them, land use data is based on high-definition satellite maps (Baidu Maps), on-site surveys and measurements, and GIS database statistics of built-up areas within the third ring road of Xi'an city. Land use data is mainly used to calculate a series of characteristic indicators of the built environment, such as land use properties and building area, in the area of rail transit stations. The source of obtaining passenger flow data for rail transit is the operation company of Xi'an Rail Transit Transportation Group Co., Ltd. The selected time period follows two principles: one is to avoid special periods such as holidays. The second is to ensure that the collection period covers the complete subway operation time every day, and the collection time is continuous for one week, which is used to calculate the number of passengers entering and leaving the rail transit station. Social development data and economic level data are sourced from publicly available online data and field research.本数据集主要涵盖轨道交通站点土地利用数据、轨道交通客流数据、社会发展数据以及经济水平数据。其中，土地利用数据基于高清卫星地图（百度地图，Baidu Maps）、现场勘测测量，以及西安市三环路内建成区的地理信息系统（GIS）数据库统计所得，主要用于计算轨道交通站点周边区域建成环境的一系列特征指标，如土地利用性质与建筑面积等。轨道交通客流数据来源于西安轨道交通集团有限公司（Xi'an Rail Transit Transportation Group Co., Ltd.）的运营部门，所选时段遵循两项原则：其一为避开节假日等特殊时段；其二为确保采集周期覆盖每日完整的地铁运营时长，且采集时间连续一周，该数据用于计算轨道交通站点的进出站客流量。社会发展数据与经济水平数据则来源于公开网络资料与实地调研。
